Patent DE-19710869-A1 (DE)
Title: Piston engine directly-controlled cartridge valve seal
Inventor: OTTERSBACH RAINER
IPC: F16K11/07
Filed: 1997-03-15
Abstract: A seal arrangement for a directly-controlled cartridge valve is push-fit into a drill hole within a hydraulic system which varies the valve control opening and closing times within a piston engine. To minimise the leaks caused by radial play between the cartridge (5) ring cross-pieces (8, 9, 10) and the bore hole (23) wall (24), the cross-pieces (8, 9, 10) on the cartridge (5) mantle surface (6) have a smaller diameter than the drill hole (23) and bear circular grooves (14, 15, 16).  Sheer-resistant ring seals (17, 18, 19) are also positioned in the circular grooves (14, 15, 16), preventing hydraulic leaks between the seals (18, 18, 19) and cartridge (5), and between the seals (18, 18, 19) and the drill hole (23) wall (24).

Title: Valve for e.g. vehicle braking system
Inventor: FEIGEL HANS-JOERG DR
IPC: F16K31/06
Filed: 1997-03-18
Abstract: A three/two-way valve for a vehicular braking system with brake- and drive-slip regulation. The valve has first and second controllable openings located between an inlet chamber (30) and a first outlet chamber outlet chamber (36). The closure (35) for the first opening is not pressure-compensated. The closure (46) for the second opening is pressure-compensated, or has a differential surface which is different to that of the opening cross-section. A valve chamber (40) connected to the valve inlet chamber (30) is connected with a second outlet chamber (44) via a through hole (38,60). A piston (41) is sealingly guided through this through hole. The piston connects on the valve chamber with a working surface so as to load the second closure in the closing direction as pressure builds up in the valve chamber.

Title: Control of a flame cutting machine with an autogeneous cutting torch
Inventor: KOUKAL ANTON
IPC: B23K7/10
Filed: 1997-08-08
Abstract: The method concerns control of a flame cutting machine (10) with an autogeneous cutting torch (12) which is numerically guided along the cutting path.  The distance between the torch and the workpiece is controlled on the basis of signals from a capacitance measuring bridge (18) with a sensor electrode mechanically attached to the torch.  The bridge (18) is continuously or semi-continuously supplied with a high-frequency voltage for which the impedance of the capacitor (19) is substantially independent of its ohmic resistance. It is also fed with a voltage of substantially lower frequency for which the impedance of the capacitor (19) depends on its ohmic resistance.  The high-frequency detuning signal from the bridge is used to control the distance between the torch and the workpiece, while the low-frequency signal is used to establish the state of the flame.  The claimed apparatus includes high-frequency and low-frequency voltage generators (42, 43) for supply of the b ridge (18).

Abstract: Determining the presence of auto-antibodies (AAb) to thyroid stimulating hormone (TSH) receptor (TSHR) in a biological sample, using a receptor binding assay, is characterized by the use of a functional recombinant TSHR (rTSHR) as TSHR composition. Determining the presence of auto-antibodies (AAb) to thyroid stimulating hormone (TSH) receptor (TSHR) in a biological sample, using a receptor binding assay, is characterized by the use of a functional recombinant TSHR (rTSHR) as TSHR composition. Recombinant TSHR is bound via a selective antibody (anti-TSHR-Ab) to TSHR to a solid phase. The bound rTSHR is purified by washing and then transferred to an affinity-purified immobilized rTSHR (rTSHR(imm)). The biological sample is reacted with: (i) a TSHR composition and (ii) a labeled bovine TSH (bTSH). The presence of Aab is determined by the amount of bound, labeled bTSH in from the fluid phase-separated complex from bTSH, especially TSHR-Aab with TSHR. Independent claims are also included for : (1) a reagent kit comprising the ingredients described above; and (2) the use of a low-molecular fraction of human serum or its derivatives, two-valent metal ions and/or sulfate group comprising polysaccharides, for increasing the binding of TSH to a TSHR in a receptor binding assay.
